s'PEcIFIcATIoN forming 5m of Letters Patent No. 627,872, dated June 27, 1899.

Application filed May 11, 1898. Serial No. 680,347. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS J. MCBRIDE, a subject of the Queen of Great Britain, residing at Toronto, in the Province of Ontario and Dominion of Canada, haveinvented newand useful Improvements in Heading Attachments for Harvesters and Binders, of which the following is a specification.

My invention relates to heading attachments for harvesting and binding machines for severing or cutting the heads from the cut straw, which heads are conveyed away to any convenient receptacle and the straw packed so as to form a bundle or gavel and then tied. The object of the invention'is to provide an improved construction of header and connections, whereby I secure important advantages with respect to efficiency in operation.

In the accompanying drawings, Figure 1 is a side elevation showing an ordinary harvesting and binding machine with my improvements applied thereto. Fig. 2 is a longitudinal section of the same. Fig. 3 is a perspective view looking from the rear. Fig. 4 is a rear View, partly in section. Fig. 5 is a detail perspective view of the grain stop and knife. Fig. 6 is an elevation of a modified construction of knife and means for operating the same. Fig. 7 isacrOss-section through the upwardly-extending curved arms and the circular knife.

In the said drawings the numeral 1 designates the grain-platform, which receives the grain out by the knife or sickle. At the stubbleward end of this platform is an inclined elevator (not shown) for elevating the cut grain from said platform to the binder plat-. This elevator may consist;

The numeral 15 designates the tail=board at the lower end of the inclined binder table or platform, 16 the packers, and 17'the needle.

The parts so far described may beof any ordinary or suitable construction and form no part of the present invention except in combination with my improvements.

Located in rear of the upper rollers at and secured to the binder table or platform is a grain-stop 18, consisting of a base 19, provided with holes for the passage of bolts or other fastening means, and two upwardly-extending curved arms 20, pointing in the direction from which the grain comes from the harvester, with a space betweenthe ends and the platform or table 3. These arms are contracted at the ends, so that the space between the ends is narrower than the space between the arms at their junction with the base 19. (See Fig. 5.) One of these arms is formed with a cutting -edge. Located between said arms is a circular knife21, which is mounted upon a shaft 22 and driven by a'belt 22 from the shaft 23 of the sprocket-wheel 10, so that as said wheel is rotated the shaft and knife will be correspondingly rotated. At one side of said grain-stop is a. downwardly-extending trough or receptacle 24, which reouter end, over which passes an endless belt or apron 29, provided with transverse cleats 30. This belt or apron also passes over aroller 31'on the shaft 23, the latter passing through the inner ends of said side rails.

Stubbleward of the shaft 6, at one side of the binder-table, is a slide 36, having a groove 37, with which engages a rib 38. By moving this slide in and out the distance which the heads of the grain project from the bindertable over the trough can be regulatedthat is to say, said slide acts as a guide for the cut grain as it'is delivered to the binder-table.

The numeral 39'designates an endless belt passing over the roller 5 and over a roller 40,

2 'ee'asve located underneath the binder-table, and its object is to carry the grain to the lower end of the binder-table.

The operation is as follows: The machine is drawn across the field, as usual, the knife or sickle cutting the grain, which is conveyed by the inclined elevator to the upper end of the machine, from whence it falls to the binder platform or table. The grain will now be caught by the grain-stop a short distance at one side of the heads, and the heads will be cut off or severed by the knife and the cutting edge of the grain-stop and will fall into the trough, striking the inclined bottom and falling onto the couveyer, which will carry them to a wagon or other receptacle. The stalks or straw will be formed'into gavels or bundles by the packers and will be tied by the needle in the ordinary manner.

In the modification shown in Fig. 6 I employ a straight reciprocating knife instead of a: circular one, which is connected by an arm 31 and eccentric-strap 34: with an eccentric 35, secured to the shaft 23.

By my improvements the heads are rapidly severed or cut from the stalks and can be subsequently threshed by any suitable machine, and the-re will be no loss of straw, as is the case where the heads are out 01f from the standing grain and the straw left on the ground.

It is obvious that my improvements can be used in connection with a low-down harvester with or without a binding attachment, as well as with an elevated one, as shown, without departing from the principle of the invention.

Having thus fully described my invention, what I claim is 1. In a harvesting-machine, the combination with the inclined table or platform, of the grain-stop comprising the base seen red to said table and two curved arms inclining upwardly and, pointing in the direction from which the cut grain comes, and one of said arms formed with a sharpened edge, and the the grain-stop secured thereto com prising the base and the curved contracted arms, the

knife located between said arms, the trough at one side of said grain-stop, and the conveyer, substantially as described.

4. In a harvesting-machine, the combina tion with the binder table or platform, the packers, theneedle and means for operating the same, of the grain-stop, the knife, the

trough or hopper, the couveyer, and means for operating the knife and couveyer, substantially as described.

5. In a harvesting-machine, the combination with the binder table or platform, the needle and means for operating the same, of the trough or hopper, the conveyer and. the grain-stop comprising the two curved arms inclining upwardly and pointing in the direction from which the grain comes and contracted from the base to the ends and one of the said arms formed with a cutting edge and the heading-knife located between said arms, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
